It's pretty simple as far as I'm concerned.
On the one hand you have "your team."
On the other you have "players you like or dislike."
When you can add a "favorite player" to "your team" well that's just icing on the cake.
That's how I felt when we picked up Bledsoe and drafted Roy.
When your team adds a player you dislike, you suck it up and you root for the best for your team.
That's how I felt about Deion, Keyshawn, Terry Glenn, and probably a few others. And that's exactly what I'll do with Terrell Owens.
If we pass on him, so be it. But if we sign him, then he's a Cowboy, and I'll root for him to do his best and help the team succeed.
Everyone loves Key now and misses him, but when we brought him in, he was a "cancerous dick who's on the downside of his career." I pretty much agreed with that sentiment, but I was willing to give him the benefit of the doubt and root for him since he was a now a Cowboy. And see, he proved himself and became an asset.
Why wouldn't I give Owens the same opportunity?
For the record, I'm neither an "old school" fan or a "newbie." As my username suggests, I started rooting for the Cowboys in the early 80s when I was a kid. I've stuck with them through thick and thin, so I'll certainly stick with them through the Terrell Owens chapter of their story.
